BOBBIN FOR TWISTING AND DRYING YARNS.

SPECIFICATION forming part of Letters Patent No. 767,438, dated. August 16, 1904.

Application filed October 13, 1902. Serial No. 127,156. (No model.)

To (all 7U7b07l'l/ it many concern:

Be it known that LGnoRens POURE, a citizen of the Republic of France, and a resident of Boulogne-suri\ler, France, (and whose postal address is Boulogne-sur-lVIer, Pas-de-Calais, France,) have invented certain new and useful Improvements in Bobbins for Twisting and Drying Yarns, of which the following is afull and complete specification, such as Will enable those skilled in the art to which it appertains to make and use the same.

Solid wood bobbins are universally known and also tubular metal bobbins,which are perforated in order to introduce a liquid into the wound yarns. I

The object of the present invention is to provide a bobbin of this kind made entirely of light sheet metal which in its form resembles exactly a wooden one and can therefore be used without diificulty in all twisting-frames now existing and other analogous machines to replace the wooden bobbins.

The improved bobbin is light. It resists mechanical strain and dampness, and, besides this, the assemblage of the separate parts may be made in a strong manner. A further advantage of the said bobbin is that although it presents exactly the same appearance as a solid wooden bobbin a space has been provided in the interiorfor the free circulation of the air, so that the holes or openingsnvhich'are at equal distances from each other, permit the dry air to penetrate into the interior of the layers of thread,thus enabling the wound yarn to dry quickly. Consequently by means of the present bobbin the subsequent unspooling for drying the thread may be dispensed with.

In the accompanying drawings, Figure 1 is avertical section of the bobbin. Fig. 2 shows the bobbin-tube in vertical section and in top view. Figs. 3 to 6 are sectional views with corresponding plans of all the component parts.

In the figures, A is the tube, formed by be employed.

bending a piece of sheet metal. The two edges simply meet one another and are kept together only by the bending,without soldering or overlapping. The tube is supplied at both ends with an annular shoulder a, and its whole length is provided with small ventilation-holes a, placed at equal distances from each other.

The tube A is fixed, by means of its shoulders a and of the folding of its underneath edges, on the stamped piece B, Fig. 3, in which the piece C, Fig. 5, is sheathed and at the same time made fast by folding.

The top of the bobbin is also composed of two stamped pieces D and E, Figs. 4 and 6, placed on the tube A and also made fast by folding of the corresponding edges. The pieces C and E are held in the line of the axis of the barrel, and thus furnish a support for the twistingmachine spindle, which passes freely axially from end to end of the bobbin.

Aluminium or any other suitable metal may Also in place of the holes a ventilation openings of any shape may be made in the tube A.

I claim A bobbin for twisting and drying yarns, consisting of a tubular sheet-metal barrel having perforations therein and having an annular shoulder on each end, the top and base of the bobbin being formed each of a stamped piece bearing against the shoulder and having at its outer periphery an inwardly-folded flange and a second stamped piece held by said flange, and having a tubular central body, said tubular body being placed in the line of the axis of the barrel so as to support the twisting-spindle.

In witness whereof I have hereunto set my hand in presence of two witnesses.

GEORGES POURE.
